Application filed June 16, 1924, Serial No. "120,411; i

My invention relates to improvements in one tip chalkers, and the objectof the invention is to devise a simple device for holding chalk forchalking cue tips so that it will always be easily gotten at, in whichthere will be no danger of the holding string wearing out, in which thebreaking of the pins holding the string is eliminated, in whichsutficient holding string may be contained so that there will be nodanger of the string being broken or the pins loosened by the jerking ofthe user upon the string during the operation of chalking, and in whichmeans is provided whereby the winding mechanism can only be operated bythe pro prietor, and therefore cannot be tampered with by any otherperson, and it consists essentially of the arrangement and constructionof parts hereinafter more particularly explained.

Fig. 1 represents a perspective view of my device.

Fig. Fig. 1.

Fig. 3 is a sectional view taken at right angles to Fig. 2 on line 3-3looking in the direction of arrow.

Fig. 4 is a view in elevation looking in the direction of arrow Figure 2from the line 44.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 indicates a cylindrical casing provided with heads 2 and 3 which areconnected together by cross-bolts 4.

5 is a bracket by which the holder may be secured in position eitherbeneath the 2 is a cross sectional View through billiard table or in anyother suitable position. The casing 1 is provided. with acircumferential slot 1 of sufficient width to permit the passage of ahand therethrough, the edges of which are turned inward, as indicated at2*, so as to present a smooth edge to contact with the holding string ofthe chalk holder.

6 is a stud shaft upon which is mounted a drum 7 upon which is wound aholding string 8, being secured at one end to the central core of thedrum. The drum 7 is so positioned that the centre sleeve thereof isslightly belowthe lower peripheral portion of the forward edge of theslot 1 so as to permit the free passage of the cord or string 8horizontally forward without triotio'nally engaging the slot edge andthus become worn.

9 is a chalk container of the type commonly employed in which the chalk10 is secured.

11 is a pinion mounted upon the stud 6 and formed integral with the drum7.

12 is an arbor ext-ending through the head 2 of the main casing andprovided at its outer end with a squared portion 12.

13 is a supplemental frame secured within the main frame preferably tothe head 2,

and in which is journalled the arbor 12. v

14 is a helical spring seoured'at one end to the arbor 12 and at theopposite end to an enclosing cylindrical casing 15.

16 are teeth or pins extending outward from one faceof the casing 15,and with which a dog 17 engages to prevent the rotation of the casing inthe direction of the pull of the spring.

18 is a gear wheel secured to'the arbor 12,

and in mesh with the pinion 11.

19 is a key provided with an internal portion 19 with which the squaredportion 12 of the arbor engages. The key 19 may be readily attached atany time by the proprietor on the operating end of the arbor 12, and thespring wound to the required tension, being held in its wound positionby the dog 17. When it is desired to chalk a one, all that it isnecessary to do is to pull the chalk retainer outward from the casing 1to any extent desired, chalk the one tip and then release the retainerso that the spring 14 rotates the drum in a contrary direction to rewindthe string 8 thereonto.

From this description it will be seen that I have devised a very simpledevice which will absolutely eliminate any danger of the holding stringbeing worn'out during its operation, which will have a large stringholding capacity, and therefore there will be no danger of the stringrunning short and. the holder being strained by the user of the chalkholder jerking upon the string, and which at the same time willeliminate any danger of the spring being broken or the spring beingloosened from a similar cause, and in which the mechanism will beentirely under the control of the proprietor so that it cannot betampered with by any other person.

What I claim as my invention is:

A one tip chalker comprising a cylindrical easing having a peripheralslotted opening in 1ts lower portlon, the ends of the slot extending inhorizontal alignment and of sulfieient width to permit the passage ofthe operators hand, a shaft journalled in the ca s-- ing a drum mountedon the shaft so that y the lower peripheral portion of its centre holdersecured to the free end of the cord, a supplemental shaft geared to-the'aforesaid shaft, a spring drive to such supplemental shaft, a ratchetwheel carried by the supplemental shaft, a dog coaeting therewith, and15 a key member adapted to be detaehably con neoted to the external endof the supplemental shaft.
